Investigations were launched after petitions were received from companies in Illinois and Texas.
The International Trade Commission has determined that imports of stainless steel flanges from China are materially injuring U.S. industry because the government of China is subsidizing those exports to the United States, according to a Federal Register announcement Monday.
The ITC filed its determination in the investigation on May 29, it said.
The Commerce Department in April finalized countervailing duties for imports of stainless steel flanges from China.
Commerce will instruct U.S. Customs and Border Protection (CBP) to collect cash deposits at a rate of 174.73 percent for Both Well (Jiangyan) Steel Fittings Co. Ltd., Hydro Fluid Controls Ltd., Jiangyin Shengda Brite Line Kasugai Flange Co. Ltd. and Qingdao I-Flow Co. Ltd., for their failure to cooperate in the investigation, as well as a subsidy rate of 174.73 percent for all other Chinese producers and exporters of these steel flanges, Commerce said in an announcement Tuesday.
The ITC started the investigations Aug. 16, 2017, after the commission and Commerce received petitions from Carol Stream, Ill.-based Core Pipe Products and Houston-based Maass Flange Corp.
